Definitions

  • the present invention generally relates to personal protection systems for use in medical environments, such as surgical environments, to protect patients from contamination during medical procedures, and to protect medical professionals from exposure to airborne contaminants and bodily fluids. More particularly, the present invention relates to protective coverings of personal protection systems and controls for helmets of personal protection systems.
  • Personal protection systems are known in the art. Personal protection systems are worn by professionals throughout the medical field, such as surgeons, during surgical procedures. Personal protection systems are used in surgical procedures to provide a sterile barrier between the wearer and the patient.
  • One such system is disclosed in U.S. Patent No. 5,054,480 .
  • the traditional system includes a helmet that supports a toga or a hood. This assemblage is worn by surgical personnel that want to establish the sterile barrier.
  • the toga or the hood includes a transparent face shield.
  • the helmet includes a ventilation unit with a fan. The ventilation unit draws air through the toga/hood so the air is circulated around the wearer. This reduces both the amount of heat that is trapped within the toga/hood and the CO 2 that builds up in this space.
  • control buttons associated with a personal protection system. At a minimum, these control buttons are provided to give the system wearer some control over helmet fan speed. If a personal protection system also includes a communications sub-system, these control buttons are provided to allow the system wearer to control such variable as speaker volume or microphone active/mute.
  • a personal protection system with a light can include a control button that allows the wearer to regulate the on/off state and intensity of the light.
  • buttons are mounted to the outer shell of the system helmet. Once the system is fitted to the wearer, the buttons are located above head.
  • Such a system is disclosed in the Applicants' Assignees U.S. Pat. Pub. No. 2007/0028372 Al , the contents of which are explicitly incorporated by reference.
  • the wearer then actuates these buttons by pressing the section of hood that covers the button. This does provide the individual with direct control of the environmental features of the system.
  • this arrangement is not without its own disadvantages.
  • the location of the buttons, above the head is awkward to reach. Further, in some surgical procedures, immediately above the head of the surgical personnel is a light.
  • the present invention provides a personal protection system for providing a sterile barrier between a user and an external environment.
  • the system comprises a helmet designed to be worn on the head of the user.
  • the helmet includes a support structure and a ventilation unit with a fan supported by the support structure.
  • the ventilation unit discharges air toward the user.
  • a chin bar depends from the support structure.
  • the helmet may also include a communications module that allows the user to speak to other personnel without having to shout through the hood.
  • a hood or toga drapes over the helmet.
  • the hood is designed to fit loosely over the helmet and typically only extends a short distance below the individual's neck or shoulders.
  • a toga is a garment that includes the hood and typically covers more of the body, such as from chest to near the knees and the arms.
  • the hood includes a filter section for filtering air drawn into the hood from the external environment by the ventilation unit.
  • the hood includes a flexible and transparent face shield.
  • the face shield includes a top portion, a bottom portion, and a sealing perimeter.
  • the hood has an opening in which this shield is seated. The shield is sealed to this opening such that the shield perimeter overlaps the section of the hood that defines the shield opening.
  • the face shield is mounted to the helmet with a first radius of curvature along the bottom portion and a second radius of curvature along the top portion.
  • the first radius of curvature is smaller than the second radius of curvature.
  • this geometry is created by providing the helmet and shield with complementary mounting components so that, when the hood is placed over the helmet and the mounting components are engaged, the shield bends to develop this curvature.
  • the relatively wide radius of curvature adjacent around the top of the shield reduce glare that results from light being reflected off an inside surface of the face shield.
  • the smaller radius of curvature adjacent the bottom of the shield increases the wearer' s field of view outside of the shield.
  • buttons for regulating the environmental assemblies of the system are mounted to an inner surface of the chin bar.
  • the individual readily accesses these buttons by simply pushing the buttons against the chin bar.
  • the individual is able to press the buttons by pressing over the portion of the hood that covers the buttons.
  • the individual is able to depress buttons without breaking the sterile barrier.

  • a personal protection system is generally shown at 20.
  • the personal protection system 20 is shown to include a helmet 22.
  • the personal protection system 20 also includes a protective covering, a hood 24, with an integrated face shield 60 for draping over the helmet 22.
  • This hood 24 may only cover the upper torso and/or arms of the wearer. Alternatively, the hood may by be part of large garment, often called a "toga,” that covers more of the wearer.
  • System 20 creates a sterile barrier between the wearer and an external environment.
  • the system 20 is useful in many medical environments, but is particularly adapted for use in surgery to protect patients from contamination during surgical procedures and to protect medical professionals from exposure to airborne contaminants and bodily fluids.
  • FIGS. 2 and 2A illustrate the helmet 22.

  • This filter section is positioned to above the intake for the ventilation unit 36.
  • An intake grid 54 (see FIG. 12 ), that is part of the helmet 22, prevents the filter section 52 from being drawn into the helmet by fan 38.
  • Hood shell 50 itself is formed from a barrier fabric.
  • the barrier fabric is as a multilaminate nonwoven fabric comprised of polyethylene, polypropylene, or polyester, or any combination thereof, to prevent fluids and particulate from passing through the shell 50.
